Initial analysis

The property at 831-833 San Jose Ave in Bernal Heights is a two-unit, two-story multi-family residential building constructed in 1909, currently owned by Valerie H. Lee and Darren Lee. The building has a significant history of compliance issues, particularly regarding unauthorized unit conversions and renovations. Most notably, from 2001-2005, the building underwent a series of permit applications and violations related to the removal of an illegal kitchen on the first floor, which had been installed without proper permits. More recently, there have been serious concerns regarding lead paint hazards (2017), multiple building code violations including electrical issues, building safety concerns, and sanitation problems (2007-2020), as well as persistent issues with an unauthorized garage unit that remains an active violation as of 2011. A 2020 complaint described the illegal unit as suffering from severe flooding issues and multiple interior code violations that made it "unsafe to live in." Recent building permits from 2006 show efforts to address various maintenance issues including interior and exterior painting, basement concrete repairs, and roof leaks, though these permits are now expired.

The building's current condition is documented through recent 311 calls (2023-2024) primarily related to street cleaning and parking violations near the property. Planning records indicate a completed two-unit condo conversion process, though there are historical records of unauthorized third unit claims. Multiple inspections and enforcement actions have been taken over the years, with some violations being closed or abated, while others remain unresolved or in process. The property has also been subject to various tenant complaints regarding heating issues, plumbing concerns, and unauthorized modifications, particularly during the period from 2007 to 2020.

Risk rating

How 831-833 San Jose Ave's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
